Nintendo Switch OLED Immediate black screen/crash when booting into OFW CFW etc but works fine in hekate

[obnoxiousmods]

I just installed a picofly into oled
Mod chip works great
Console turns on etc Controller works, charges etc

I can get into hekate but as soon as I pick OFW or CFW it black screens (NO LOGOS OR TEXT + CONSOLE IS ON), if i do volume + power to skip payload and go into OFW it also black screens with or without an SD in

Any ideas on this issue? Any way I can diagnose

its obv a chip installation problem, recheck your pins with diode mode and with an electronic microscope

all my diode readings are perfect

3v3: 858
D: 792
A: 762
C: 766
B: 1.550
no shorts to ground

should i just redo everything???

Does it still boot normally if you remove the chip? Seeing a lot of people coming across issues with these clone chips.

There have been some issues with clone boards where they used the wrong resistor values.
Also some OLED devices need other resistor values because of the brand emmc they are using.
It might be worth checking the picofly sticky thread for more details.

Hi Obnoxiousmods,
I have the same issue. when you installed the new chip, did you just replaced the chip or all the ribbons? Unfortunately, unlike you i ordered only 1. So, i have to order another replacement to see if this is the case. TIA!

I ended up replacing everything, also PLEASE backup your NAND as soon as possible before you do anything else always back up your nand, as well as your keys PRODINFO+KEYS most important but id make a rawdump or atleast a dump of all partitions other than USER
